ABSTRACT:
A refinery petroleum gas recovery apparatus driven by normally wasted heat, comprising primarily the cooling system, the heat exchanging petroleum gas recovery system, and the appropriate peripheral equipment, wherein the wasted heat from the refining process is used as a power source for creating a vacuum cooling function to cool the water being heat exchanged with the petroleum gas down to the temperature of 12.degree.-13.degree. C. The heat in the gas is removed and the gas is condensed into liquid for reuse. The petroleum gases ethane, propane etc. which are ordinarily burned in the torch tower can now be recovered for reuse. The air pollution created from the burning of the gases in the torch tower is eliminated. Thus the apparatus has a high industrial value.
